[LG Optimus 2x] JohnRogers:
Yes, I have the international version.

While true, it seems that the browser should be a perfect example of where that extra core would come in very handy, yet the performance doesn't differ from what the Nexus S is performing if you compare page loading time.

Any suggestions of benchmarking scripts/apps that are intended for SMP configurations? I would very much like to figure this out.

Some more info from dmesg, pretty much identical with anandtechs model:
